Abstract

In this work, a novel polymer electrolyte membrane water electrolyzer (PEMWE) test cell based on hydraulic single‐cell compression is described. In this test cell, the current density distribution is almost homogeneous over the active cell area due to hydraulic cell clamping. As the hydraulic medium entirely surrounds the active cell components, it is also used to control cell temperature resulting in even temperature distribution. The PEMWE single‐cell test system based on hydraulic compression offers a 25 cm2 active surface area (5.0 × 5.0 cm) and can be operated up to 80°C and 6.0 A/cm2. Construction details and material selection for the designed test cell are given in this document. Furthermore, findings related to pressure distribution analyzed by utilizing a pressure‐sensitive foil, the cell performance indicated by polarization curves, and the reproducibility of results are described. Experimental data indicate the applicability of the presented testing device for relevant PEMWE component testing and material analysis.

一种新型的基于液压电池压缩的聚合物电解质膜电解测试系统

在这项工作中，介绍了一种基于液压单电池压缩的新型聚合物电解质膜水电解槽（PEMWE）测试电池。在该测试电池中，由于液压电池夹紧，电流密度分布在活性电池区域上几乎是均匀的。由于液压介质完全围绕活性电池组件，它还用于控制电池温度，从而实现均匀的温度分布。基于液压压缩的PEMWE单电池测试系统提供25 cm2的有效表面积（5.0×5.0 cm），可在80°C和6.0 a/cm2的温度下运行。本文件中给出了设计试验室的结构细节和材料选择。此外，还描述了通过使用压敏箔分析的压力分布、极化曲线指示的电池性能以及结果的再现性的相关发现。实验数据表明，所提出的测试装置适用于相关的PEMWE组件测试和材料分析。
